This feels like we've let the plugin API get slightly more
access to QEMU's internals than is ideal. Whether an area
of memory happens to be an IO memory region or a memory-backed
one (or whether a device is implemented with one region or
three, or what names we happened to assign them) is kind of
a QEMU internal implementation detail.
